X230 Tablet Docking Station Compatability

The reference guide is not very clear. Is the X230 Tablet compatible with any of the USB 3.0 docking stations:

ThinkPad Port Replicator Series 3 with USB 3.0 (433615W)

ThinkPad Mini Dock Series 3 with USB 3.0 (433715U - U.S.)

ThinkPad Mini Dock Plus Series 3 with USB 3.0 – 90W (433815U - U.S.)

ThinkPad Mini Dock Plus Series 3 with USB 3.0 – 170W (433835U - U.S.)

Officially, according to the guide it only shows the ultrabase, however when you search for accessories by selecting the X230 Tablet it brings up others, but not the USB 3.0 series. The X230 Laptop is compatible.

Although it may not be worth the price as it seems to only have 1 USB 3.0 port and the rest are 2.0, price seems to be a $40 premium for the 1 USB 3.0.

When it is on the docking station does it lock out the native USB ports in the chassis of the X230T? An older Toshiba I had reccomended against using the Laptops USB when docked.
